1. Product description
FS00208 Sensor is a Multi in one sensor which can simultaneously monitor the concentration of particulate matter, formaldehyde, temperature and humidity in the air. Based on the principle of laser scattering, the monitoring of particulate matter concentration can continuously collect and calculate the number of suspended particulate matter with different particle sizes in the air per unit volume, that is, the distribution of particulate matter concentration, and then convert it into mass concentration. The monitoring of formaldehyde concentration is based on the principle of electrochemistry and has the characteristics of high accuracy and stability. Temperature and humidity sensors are imported from Switzerland. Particulate matter concentration, formaldehyde concentration, temperature and humidity are combined and output in the form of universal digital interface.
This sensor can be embedded in all kinds of instruments and apparatuses or environmental improvement equipment that are related to air quality and provide timely and accurate concentration data.
